Microsoft Advertising has now released a new ad SDK to help developers to increase revenue by giving advertisers more options to present ads.

The new ad SDK will enable rich media ad formats including Expandable Ads that can include click to video and click to image capabilities. These ad experiences are intended to deliver immersive experiences that engage users within the app experience.

According to eMarketer, advertisers are projected to invest 44.2% of their total mobile budget on display advertising (rich media, banners and video) on mobile in 2013, and the new SDK allows Windows Phone developers to take a chunk of this cash.
